Davenport, S. Williams pull out of Tokyo Tournament

Jan 31 - Feb 5 is the Toray Pan Pacific Open Tennis Tournament (Tokyo, Japan). Both Davenport and Williams have withdrawn - Davenport for the AO ankle injury, and Serena for "more practice time":

"I feel like I need more practice time on the court in order to compete at the highest level," she said.

Sounds like a comeback attempt to me.
